© 2015 IEEE. This paper presents a scalable 32-channel neural recording platform with real-Time, on-node spike sorting capability. The hardware consists of: (1) an Intan Technologies RHD2132 neural amplifier; (2) a low power Igloo® nano Field Programmable Gate Array (FPGA) for spike detection and template matching; and (3) an EZ-USB FX3TM peripheral controller for transmitting the data to a computer over USB 3.0. The system is implemented in 2 parts, the first board (headstage, 51mm×33 mm) contains the RHD2132 and FPGA and is intended to be in close proximity to the animal, while the second (80mm×56 mm) is a combination of an FX3 development board with a custom interface shield. Graphical User Interfaces (GUI) for controlling the system, displaying real-Time raw & template matched data, and for template generation with WaveClus. Noise performance of below 1 LSB (∼3 μV) was measured and system power consumption (excluding FX3) of 15.1mW while idle, 34mW while outputting raw data and 34mW while outputting template matched results.
